If you have an MCX with an Eotech, will it go nuclear?

I don't have an MCX, but my 2 cents is that at least Sig seems to has done the right thing by owning up to a potential safety hazard and issued a recall. It's seems like they are making it as painless as possible for the customer.

I would say if you liked your MCX before this happened, you will still have the same experience after you get it back (hopefully).

It's not like Eotech, where L-3 blatantly covered up defects to their users until they got caught defrauding the government.

I personally had my MCX 300 blkout discharge while loading from an open bolt.
I find it interesting that in the email sent, it is stated that they have "not reported in the field" of this happening. As soon as it happened, I was on the phone with Sig CS and returned it to them.
Then posted on this site to see if anyone else had this issue.
My serial number does not fall within the numbers posted in the email. So I called CS and told them this. I was told to register again and it would be taken care of.
I will wait. No worries here.

Any verifications yet about this firing pin retaining pin? Whether it's really "immobile" (Welded/pinned/peened) or just "captive" (retained)?

Thanks- looks like it was an edit so I missed that - sorry;

This actually makes it far less uncomfortable... the idea of getting a BCG/carriage that wasn't able to be disassembled was to say the least, concerning.

One less AR-compatible part (firing pin) but rather that than a risk of a slam fire.

Well I was actually in the process of shooting my 300blk MCX when I felt my phone vibrating in my pants. It was my LGS so I immediately got excited as I thought forsure it was my stamp arrival for my Octane 9 as I'm expecting it any day.

I even answered the phone, "oh I've been hoping to hear from yall soon."
however he then informed me about the mcx recall. I just went through the online registration which I did a while back so I guess I will now just wait for my box to arrive.

I got the same email, of course their customer service hours suck. I have a Hiperfire trigger in mine. So sounds like if don't have a Giessele, I am going to be screwed. I was happy with it, until now. I am ready to take the Hiperfire out, and dump the damn thing. Let someone else put up with is BS. I will attempt to call CS tomorrow to see if the can restore my faith in it.

I just got off the phone with them a few mins ago, I was on hold for right at 25 mins. Anyway you will have to send your rifle in but the good news is they will install the Geissele trigger and you will get your hiperfire back so you will just have to put that in something else. If you don't have anything else, then congrats you now have a reason to get a new gun.

I have a Super Dynamic Enhanced trigger in my MCX. I was told that I would get my entire trigger assembly back and that a new Geissele trigger specifically designed for the MCX was going to be installed.
I am wondering if maybe it depends on which model Geissele you have (or some other maker) if you get your entire trigger replaced or just some part?

MCX BCG replacement/recall

On hold with SIG CS for about 20 mins. My MCX falls within the serial numbers that required a call to CS for instructions. However, the rep (Mike) only asked about whether i had any aftermarket parts i.e. triggers. Other than that he set up a return box for me and I was all set. I was concerned that I would need to send my rifle in b/c of the serial number. He also said the replacement would be nitrite coated (like my current one) and not nickel boron. The firing pin will also now be a proprietary one.

I did register online yesterday through their recall email link and the rep did not have any record of it in their system. Maybe it has something to do with the serial number and that is why you have to call in.

Overall, I was very pleased with the CS. Now the wait for the box. Hopefully, all this gets replaced in a timely manner. Most likely will take longer b/c of holidays. They are closed Monday.

Just registered my firearm for the second time and didn't get a re-assuring message after so I decided to call SIG.

Customer Service was mostly good. When I asked about the recall I was corrected that it was an "upgrade", then asked if I had an aftermarket trigger, which I do. Told him I had a Rock-River trigger and then he informed me that this trigger may no longer work with my gun and that I may have to go back to the horrible MCX Stock Trigger.

I do not want to get ahead of myself here but if for any reason my RR Trigger doesn't not work I am going to be very upset about this "Upgrade". When I voiced my concern about this potential not working all the rep said was "things change". I was speechless at the response (not trying to get frustrated before a potential issue), so I just asked again that a box should be coming with-in the week, which he confirmed.

Crossing my fingers the RR Trigger still works or SIG is in for a headache from me.

Just so I'm clear, the recall only affects the listed serial range? Anything outside that range is exempt?

Having received my Form 1 on my MCX, I'm pretty much stuck with this platform. Love the rifle and I don't really care about the 300BLK conversion but Sig is making this far from a painless ownership experience. I'm removing my Geissele SSA-E and using it for another build. Hate the idea of reinstalling the original trigger though.
 
#67 · (Edited)
I am really really really regretting this purchase. Wish I would have just spent the money on a DD, but the prospect of a piston 300blk SBR was just too alluring. I'm probably going to end up cancelling my SBR tax stamp on the gun and cancelling my conversion kit order I placed in MARCH.

This is seriously flirting with a false advertising suit in my opinion.

Quick question: is it feasible to take my MCX in to LGS and trade it in, or will I have to go through the recall 3–week process?

Want out of the MCX game.
